The phase of the following are:

1. Melting.

2. Condensation.

3. Evaporation

4. Freezing point.

When any substance change from solid state to liquid state, it is called melting.

Ice change into water is an example.

Condensation is a process in which the air is cool down and convert into liquid from, like dew.

Water drops outside cold water bottle is an example.

Evaporation is the opposite of condensation, in which the liquid become so hot that it change into gaseous form.

Water turns into vapor in hot temperature.

Freezing point is when liquid is converted into solid.

Water converted into ice in fridge is an example.

Thus, The phase of the following are:1. Melting., 2. Condensation., 3. Evaporation., 4. Freezing point.
